9.10.2.11 Setting Max. Speed ON / OFF function
|
11D
|
The value for “ Max Speed ” adjusted in menu “ Settings ” , is activated over a digital input. I.e. the unit
works independently of the controller function fi rm with this value.
Contact e.g. at ditgital input “ Digital In 1 ” (depending on device type at terminals “ D1 ” - “ D1 ” or “ D1 ” -
“ 24 V ” ).

In order to avoid a sticking or a freezing of standing fans in cold environment, the
“
motor heating
system ” can be switched on.

1 Setting “ dc brake level ”
The motor heating can be activated over a digi-
tal input.
E.g. over a freeze protection thermostats at
digital input
“ Digital In 1 ” (depending on device
type at terminals “ D1 ” - “ D1 ” or “ D1 ” - “ 24 V ” ).
Motor heating active at closed contact, if no
modulation of the controller is present (for
“ D1 ”
= Inverting “ OFF ” )
The motor heating function corresponds to the braking function in which a direct current puts the
motor into standstill. The height of the
“
brake level
”
is set in
“
Motor Setup
”
.
Setting range: 1 - 50 %
Factory setting: 5 %
A current is impressed here, which does not permit any rotation of the fans. The value required to
prevent any freezing depends on the ambient conditions and the connected motor
’ s technical data.
The setting effected is to be checked under real conditions. The higher the setting, the greater the
heating output generated in the motor (heat dissipation). The motor heating or stationary heating can
only become active, where there is no given modulation as a result of regulation.
To prevent any overheating, motor protection in the form of thermal protection installed in the motor is
required (
motor protection). The heating function is switched off when the motor protection function
of the regulating unit responds.
